Taken in 1900, this photograph shows the gas holder at St Pancras junction,
which linked the Midland Railway to the Great Northern Railway and the
London & North Western Railway. The Grade-II listed structures, which sat

the Imperial Gas, Light and Coke Company and held gas manufactured on site
from coal.
